[rp-ml] RE: Small Gears

I have had great success prototyping Gears on my FORTUS 400mc. I use a .005 slice and adjust the "road with" to minimum. How small is small? Is there a RP House in your area running one of these machines?

I remember back in the early 1990's when the RP mailing list was very vibrant and informative with issues related to Rapid Prototyping. If you saw a new rpml email come through, you read it and many times learned something. There was none of this ranting we've seen recently and just hitting the delete key as the messages come in.


Are we all just the old timers left on this list? Where have the young bloods gone? Blogs?.......Twitter?.....other lists?


The recent political rants need to move onto to a chat line please and off the rpml.


This is still a very dynamic industry, with so many things changing in hardware, software, materials, processes, etc. each month and year. I would like to hear about it and learn something.


Here's what's on my mind this morning..........


Is there someone out there who can actually RP small, usable gears for me? I'd love to move away from machining numerous ABS gears for our electronic "works like" prototype models. Anyone have some success? We do create RP gears in a variety of technologies, but they all suffer from one issue or another such as initial material strength, inaccuracies, material breakdown. After the design is proven we machine custom gears. I don't need a very long life for these typically a couple of months tops, just a quite, smooth running gear. As always timing is an issue. It's asking a lot but it's my Holy Grail.


Someone inspire me again....teach me something please.

Apparently you and others at the the University of Bath! But I assume you are TOTALLY kidding - right? !

Are you saying you are willing to start teaching and doing research, for free, in exchange for all the RepRaps, music, movies, and TV you could ever want (great idea for 2010 :-) ? How are you going to pay the farmer, and your doctor - in RepRap 'units' or RP parts :-)? Ahhhh, but then I think you will agree with me that talk is, by far, the cheapest commodity of all (actually it's one of the few things that's ALWAYS been free)? Just (half) kidding though, in order to try and rattle your notion, a bit, that there simple solutions to tough problems, probably will do. Here in the States, people often fault academicians for not having enough "skin in the game" and being sheltered from the harsh realities of living in the "real world". I guess I kind of have one foot in both worlds and so can look at things both ways, or as a series of +'s & -'s (though, sometimes, it still seems like a zero sum game).

The inkjet worked and we could deposit stuff with it. But it was a student project, so we have simply stored the results to possibly take further in the future.

And... Who needs to earn, if stuff is free? :-)

Best wishes
